Reaction Steps

41.5 g (0.409 mol) of triethylamine was added to 300 ml of dimethyl carbonate solution of 44.0 g (0.386 mol) of 4-formyloxy-2-butyn-1-ol, and cooled to 0° C. 46.9 g (0.409 mol) of methanesulfonyl chloride was dropwise added to the solution while the inner temperature was controlled to be not higher than 15° C. After the addition, this was stirred at 25° C. for 1.5 hours, the reaction mixture was poured into an aqueous saturated sodium bicarbonate solution, the aqueous layer was separated, and the organic layer was concentrated to give 72.6 g (yield 98%) 4-formyloxy-2-butyn-1-yl methanesulfonate. For use in the battery test, this was purified through silica gel column chromatography.
